NEW
PRODUCTS Lithium-ion fire extinguishers from Sea-Fire UK-based Sea-Fire has recently launched a new range of extinguishers
to deal with the threat of lithium battery fires. The extinguishers contain AVD (Aqueous Vermiculite Dispersion) which is described as ‘the only agent that contains, cools and extinguishes lithium battery fires and can be used in both portable and fixed fire safety systems, including sprinklers.’ The extinguishant works by creating a film over the fire and depriving it of oxygen, quickly putting the fire out whilst the AVD remains non-toxic to humans, plants and animals.
Sea-Fire’s AVD range is available from 500ml aerosols for small appliances aboard like mobile phones right up to 9 litre cylinders. Larger wheeled units are available on request. Sea-fire says the range of batteries that can be tackled are usually the smaller marine types found in outboards and some tenders, up to around 750Wh.

Kongsberg introduces new underwater mountable thruster with permanent magnet motor
Kongsberg Maritime has added a new size of underwater mountable thruster with a 3.7-meter propeller and 4.2 MW power output to its range. Suited to a range of vessels including drill ships, wind farm vessels, and production vessels, the new UUC PM 355 thruster delivers 81 tonnes of bollard pull and features a permanent magnet (PM) motor. The UUC PM 355 has a compact design with less space required in the machine room thanks to the integrated PM motor.
Kongsberg Maritime has more than 25 years of experience in the development of underwater mountable thrusters, which can be exchanged without the need for drydocking, while the vessel remains in the water. Installation of the UUC range can be done at depths of up to 50 meters.
“Our UUC range of underwater mountable thrusters remains a popular choice across a range of offshore applications where minimising downtime is a priority,” said Kongsberg Maritime product line manager Pasi Villanen.
Chinese outboard maker delivers first 300hp twin electric powertrain system
ExploMar, the Chinese outboard manufacturer, has delivered what it says is the world’s first 300hp twin electric power-train system to an Italian customer and successfully conducted sea trials. This marks the first global application of the 300hp twin-engine electric power train system. An 11m (36ft) rigid inflatable boat, equipped with the WAVE 300 twin electric powertrain system, carried six passengers during the test and reached a speed of 38kt. The 11m RIB, newly built and owned by the Italian pioneer in new energy marine technology AS Labruna srl, is equipped with two WAVE 300 electric outboards and two HEDB 125 batteries, delivering a total power of 600hp and a battery capacity of 250kWh, providing robust output power.
The WAVE 300 is ExploMar’s first electric outboard product, redefining electric outboard design with a ground-breaking approach. The company has applied axial flux motor technology to high-performance boats for the first time, achieving a 300hp power output in an electric outboard with lighter weight and a maximum output torque of 655Nm per unit.
